EPUB step

Splits input XHTML document, whether styled or semantic, into several pages and packages these pages as an EPUB 2 book. The result of the this step is the file containing the EPUB book.

No tab expansion for EPUB 2

By default, when generating styled HTML (that is, XHTML+CSS), some JavaScript™ code (w2x_install_dir/xed/expand-tabs.js) is added to the output file. This code computes and gives a width to all <span class=”role-tab> </span>. This allows to decently emulate tab stops in any modern Web browser. More information in About tab stops.

However, this cannot work in the case of the EPUB 2 output format because scripting is disabled in the styled HTML pages comprising an EPUB book.

Same parameters as the Split step, plus the following EPUB specific parameters (for clarity, the “epub.” parameter name prefix is omitted here):

Name

Value

Description

cover-image-url-or-file
